Patented June 24, 1930 UMTED- STATE rsr FFEQE GEORGE B. NICHOLS, OF AKRON, OHIO, ASSIGNOB TO FIEESTCNE TIRE & RUBBER COMPANY, OF AKRON, OHIO, A CORZEORATION OE OHIO MACHINE FOR INSERTING VALVES IN INNER TUBES Application filed June 7, 1829.

This invention relates to apparatus for use in inserting valves in inner tubes during the manufacture thereof.

There has heretofore been used in this art a valve hole punching machine including a mandrel over which an inner tube is slipped and a punch actuated therethrough against the mandrel to form the valve hole prior to splicing the tube in endless form. The present invention is preferably embodied 1n such a machine.

The general purpose of the invention is to provide in combinationwith a mandrel over which an inner tube may be slipped, means for supporting a tire valve substantially fiatwise against the mandrel so that the tube may be easily slipped vthereover, and means cooperating with the valve supportlng means to swing it up into a position perpendicular to the mandrel to facilitate insertion of the valve body through the valve hole of a tube.

A further object of the invention is to provide means associated with said valve supporting means for positioning and aligning the valve hole of the tube wlth a valve on said supportingmeans.

A further object of the invention 1s to provide means associated with said positioning and aligning means for depressing an inner tube onto a valve.

The foregoing and other purposes or objects of the invention are attained in the apparatus illustrated in the accompanying drawings and described below. It is'to be understood that the invention is not limited to the specific form thereof shown and described. I

Of the accompanying drawings,

Figure 1 is a plan of apparatus embodying the invention;

Figure 2 is a front elevation thereof;

Figure 3 is an enlarged section of the puncher on line 83 of Figure 2;

Serial No. 369,155.

Figure 6 is an enlarged elevation illustrating the punching operation on a tube;

Figure 7 is a similar view illustrating the tulgle positioned for insertion of the valve; an

Figure 8 is a similar view illustrating the inserting operation.

Referring to the drawings, the numeral 10 designates an elongated anvil adapted to receive an inner tube thereover and accordingly supported at one end only, as by a bracket 11. At its unsupported end the anvil 10 is formed with a die 12 with which a punch to be described is operated to punch a valve hole in an inner tube slipped onto said anvil.

, Adjacent the die end of said anvil there is provided a depressed seat 13 for valves to be inserted in a valve hole in the tubes, said seat being formed with a notch 15 so arranged as. initially to receive the edges of the bases of the valves (Figure 6) whereby the valves may be positioned therein'to lie along the anvil as shown in the above figure. Arranged for cooperation with'seat 13 is a reciprocable element 16 mounted on the anvil and provided with a forked end 17 adapted to embrace the valves above their bases, a groove 18 being formed in the top of said element to receive a valve body therein when the valve is initially positioned tolie along the anvil.

As appears from Figure 6 the forked end of element 16 is-elevated sufficiently above the anvil to engage above the center of the base of a valve supported in notchlfr and groove 18. The under surface of the element 16 is tapered from said notched end as at 19 whereby when the element 16 is actuated toward the unsupported end of the anvil, a valve lying thereon with its base in notch 15 will be swung upwardly to a vertical position by engagement of the end of the element 16 with the base, and the base will be forced onto the flat upper surface of seat 13 into which it will be depressed by the tapered surface 19, the valve being thus tightly. clamped by the element in a vertical position on the anvil.

The element 16 is reciprocable through bracket 11 and is adapted to be actuated by a plunger which may be reciprocated by a double-acting fluid pressure cylinder 21 connected at its opposite ends to pressure supply pipe lines 22 and 23.

Bracket 11 extends upwardly from anvil 10 and has an arm 24 extending from its upper end over the anvil 10. Adjacent the end of arm 24 a punching device 25 is provided for cooperation with die 12. This clevice includes a vertical sleeve 26. mounted on arm 24 in which is slidably journaled aver-' tical shaft 27 as by bearings 28 and 29, said shaft having an annular cutter 30 mounted on its lower end in a known manner which will not be described in detail. A drive pulley for the shaft 27 is provided at 31, it being journaled in top of sleeve 26 and being keyed to shaft 27 as at 32 so as to permit shaft 27 to slide through the pulley while it is being driven. A yoke 33 is journaled on the top of shaft 27 being fixed against sliding thereon as by a nut 34 and shoulder 35, and yoke 33 is hingedly connected to a manually operable arm 36 pivoted on the arm 24 and normally urged upwardly as by a counterpoise 37. A guard 38 may be provided for the cutter 30.

The cutter 30 is provided with the usual ejector 39 and a receptacle 40 is mounted below the cutter to receive the punchings, the mounting comprising a pivoted arm 41 operable by a link 42 connected to lever 36 to swing the receptacle 40 from beneath the cutter when the cutter is actuated. Pulley 31 may be arranged to be driven by a belt 43 trained over a pulley 44 on the shaft of a motor 45.

' a tire valve and formed'with. ron' s 47 insortable in the valve opening of a tube to position the opening over a valve on seat (ill 13. The inserter is mounted on a crosshead 48 reciprocable on guides 49, 49 and operable by a piston 50 in a double-acting fluid pressure cylinder 51 mounted in arm 24. Thecylinder 51 is connected to piping 52 and 53 supplying fluid under pressure thereto. A safety stop member for the inserter 46' is provided at 54 being pivoted as at 55 to be brushed aside by the operative in positioning a tube for insertion of the valve. 7 v i In order to correlate operation of the valve positioning element 16 and the in serter 46, the piping 22 and 23 is connected toa suitable valve 56 and the piping 52, 53 to a suitable valve 57, both valves being in turn connected to main supply lines 58 and 59 and bein controlled by a single rnanually operable element such as a-lever 60 so that movement of lever 60 in one direction from neutral will actuate element 16 to swing a valve from the reclined position aeaa shown in Figure 6 to the vertical position in Figure 7, an actuation of the lever 60 in the other direction from neutral will cause ele ment 16 to be retracted and the inserter 46 to be depressed to force the tube down about the valve, and actuation of the lever 60 back to neutral will cause the inserter 46 to reassume its upper position.

In operation, the operative first lays a valve V in the position shown in Figure '6, then slips a tube T onto the anvil '10 as shown and actuates the cutter 30 as illustrated in dotted lines to punch a valve hole through the wall of the tube T, next the tube T is slipped along the anvil 10 and the valve opening is engaged over the prongs 47 of the elevated inserter v46, whereupon. the element 16 is actuated to swing the valve V up into a vertical position on. seat 13, all as illustrated in Figure 7 The inserter 46-is then depressed to force the tube T down onto the base of Valve V, element 16 being at the same time retracted out of the way, this operation beingillustrat'ed in V Figure 8, the depressed position of the inserter being indicated in dotted lines. Finally the inserter is raisedto its original position ready for a succeeding operation.

Modifications of the invention obviously may be resorted to without departing from the spirit thereof or the scope of the, appended claims. The machine isadaptable for inserting bent as well as straight valves in tubes, the inserter, of course, not being used in this case, the operative passing the opening in the tube over the bent stem'and onto the base of such a valve byhand.
